Description
Radiator considering Internal Flow, Ansys Fluent CFD Simulation Training
In this case, we simulated an internal flow radiator is simulated by Ansys Fluent software. In this modeling, the hot oil is cooled with cold water so that a spiral tube in which the oil flows into a rectangular cubic chamber that Water is flowing inside it. The oil inlet velocity is 0.05 m / s with a temperature of 400 K. The water inlet velocity is 0.01 m / s with a temperature of 273 K. Both fluids are discharged to an environment at atmospheric pressure.
Geometry & Mesh
The geometry of this modeling is three-dimensional and is designed with Spaceclaim software, which consists of two parts: a spiral tube and a rectangular cubic chamber.
The meshing of this modeling has been done with Ansys Meshing software, and the total number of cells is 1615429, which can be seen in the picture below.
CFD Simulation
We consider several assumptions to simulate the present model:
- We perform a pressure-based solver.
- The simulation is steady.
- The gravity effect on the fluid is ignored.

Radiator considering Internal Flow Results
After simulating that temperature, speed, and pressure contours can be drawn, it is clear that this radiator has been able to do its job well and has decreased the oil temperature from 400 K to 363 K. The temperature of the water itself has increased by 20 during this process. The inlet speed of water and oil greatly affects heat transfer, and naturally, the outlet temperatures of water and oil can be changed.

The training was comprehensive and detailed. The balance between hot oil cooling efficiency and the effect of water and oil velocities on heat transfer was insightful. Understanding how inlet temperatures of cold water can manage oil cooling was fascinating, resulting in practical knowledge for optimizing radiator performance.

Which models are specifically used in the simulation for the radiator’s viscous effects and how do the chosen models affect simulation outcomes?
MR CFD Support –
In the simulation, the realizable k-epsilon model with Menter-Lechner near-wall treatment is used for modeling viscous effects. This model captures the effects of turbulence and its interactions with the boundary layer accurately, which in turn affects heat transfer rates and fluid flow patterns within the radiator, resulting in more precise simulation outcomes.
